This is the 4th year the Guinness World Record-setting award is making its way to Cologne and, with such a raft of big titles flexing their muscles on the show floor, you know competition is going to be fierce and every single vote counts.

Previous winners include Valve's force of nature Dota 2, which took home the title in 2011, followed by ArenaNet's MMO Guild Wars 2 in 2012. Last year's winner as chosen by you was DayZ. Who's getting it this year? Well, that's up to you.

Voting is open now and will close at 1am PT / 4am ET / 9am GMT on Monday August 18, with the winner being officially revealed just three short hours later.
